desertcart.com: CATEYE Velo 9 Wired Bike Computer | Entry-Level Speedometer and Odometer, Perfect for Beginner Cyclists, Auto Start/Stop, Easy Setup for Road, MTB, Gravel Bikes : Sports & Outdoors

Review: Easy setup except for setting specific tire size. - I've used CatEye biking computers for years on several different bikes, so I was familiar with the basic setup. But for the Velo 9 I found the mostly illustrated instructions confusing, because I wanted to specify the exact circumference of my tires to get accurate distance readings. And I didn't care to measure this manually. I might have chosen 700c but looking carefully I saw that this could give (an unspecified) difference from my own tire circumference. The solution was to choose the 205 option (which is a choice for circumference) and then increment this number the the one indicated in the table of various sizes. So following the illustrations I incremented the number (first units, then tens) to the size indicated in the table for 700-38c tires, which is 218. Pressing and holding the mode button completed the choice for size. From there everything was familiar except my installation which was different from typical, in which the magnet and sensor are mounted on a front wheel. I am using the Velo 9 on a bicycle attached to a trainer so I wanted to measure revolutions of the rear wheel. The wire from the sensor to the display is too short to reach the handlebars, but luckily my bike, a Schwinn CrissCross, has a step-through top tube that is lower than the typical male bike and the wire does reach from the rear to near the front of the top tube. One question I had about choosing the CatEye Velo 9 was what is the difference between Velo 7 and Velo 9? The answer was on the second page of the setup instructions - Velo 9 is identical except that it can calculate Calories and Carbon Offset (CO2). If I had known this I would have opted for the slightly cheaper Velo 7. I had not seen a list of differences anywhere else. I am pleased with my setup and with the displays of the Velo 9. It works well for me.
Review: Simple, basic, reliable bike computer - A great basic cyclo-computer! Here is what I like -- ++ Very easy to scroll thru the different functions -- time, distance, average speed, etc. One button! ++ WIRED connection. No cell phone interference, no extra battery, no clunky sensor. Install and forget. ++ Not too flashy, so less likely to draw unwanted attention or detract from the bike ++ Battery life in years (based on using several similar Cateye computers) What is not perfect -- -- The spoke mounted magnet needs a better mount. -- The handlebar mount is just a couple of ty-wraps -- but it does work for me. -- The CO2 and calorie functions are a bit silly for me. Got about 100km / 65 miles on my Velo 9, and it has been just what I expected. Friendly advice -- when you are setting yours up, choosing the KM vs. Miles setting is the first step. If you skip it, you cannot go back (at least, I could not figure out how). So make sure to check it when you start -- mine was set to KM and I missed it, so had to set up twice. Updated after a year -- very pleased with this cyclocomputer. It is easy to remember the functions, like resetting the trip odometer. The mount has held up well, even tho it gets removed a lot for security. Still on the original battery. Easy to read in either the sunshine or cloudy days. Overall, a solid little computer.

## Features

- ALL YOUR FAVORITE STATS: Displays current, max, and average speed, total distance, trip distance, elapsed time, pace arrow, and clock.
- BECAUSE YOU CARE: The Velo 9 also tracks calories and carbon offset.
- DON'T SWEAT THE SMALL STOPS: Caught at a red light? Stopping for coffee? We've got you covered. Your CATEYE computer knows when you've stopped and automatically stops counting time and averaging speed.
- GO THE DISTANCE: With a battery that lasts up to three years, you can install it and forget about it.

### ⭐⭐⭐⭐ Install was straight forward but can't turn it on! ...
*by A***R on August 14, 2014*

Install was straight forward but can't turn it on! Why? Because the battery came with ZERO voltage. Yup a 3 year Panasonic battery deader than dead. Checked it with my fluke 789 process meter I use for work every day. I will have to update this review after I get a chance to go out to the store and buy a new battery for a shiny new bike computer.that currently does... Nothing! ***UPDATE!! So took it on 25 mile ride today and it did great! After I had to go to a store and spend 5 bucks on a new battery. (This 2032 battery type is supposed to last 10 years on the shelf so don't know what how old it was in shelf years before I got it.) I had got this just so I could track speed, total miles, and trip miles and because the unit is small enough to go in my pack and large enough to read easily. I could see the display great even under shady trees with my polarized shades ;-) Moving thru the menu and setup was a breeze you will just need something small to hit the reset button and set button on the back. I have 29"X 2.2 Tires on my mountain bike which are not in the Auto setup selection but when you measure it out it comes to 230 CM it takes whole numbers so truncate the decimal for those who like to be exact. I had 3 other bikers on the trip out of the 9 who had different bike computers and GPS biking apps and after 25 miles we were all within a 10th of a mile. I like the wired unit because it also does the Auto on and off it "should" save the battery this time. The mount on the handle bars is a little cheap but for under 20 why should I expect something bullet proof? I am going to get some handle grip wrap and put that under the mount.⇦another reviewer idea. SO 4 out of 5 stars in my book for the handlebar mount and the battery issue.
